TO MARIA A.

MILK-COOLER.

SPECIFICATION forming part of Letters Patent No. 654.220, dated July 24,1900. Application filed October 6, 1899. Serial No. 732,790. (No model.)

To aZZ whom it may concern.-

Be it known that I, DAVID BOTHWELL, of Hannibahin the county ofOswego,in the State of New York, have invented new and usefulImprovements in Milk-Coolers, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and eX- actdescription.

This invention relates to improvements in milk-coolers.

My object is to produce a milk-cooler which is adapted to cool the milkby supporting within the can a receptacle through which cold waterisallowed to pass and at the same time so arrange it that the milk when itis poured into the can will first flow or trickle along and down theouter and cool walls of the cooling device, at the same time providingmeans at the lowerend of the can for drawing off the milk to prevent itfrom whirlpooling at the bottom, thereby obviating suction, which drawsthe dirt and other foreign substances out with the milk, but allows themilk to be drawn out evenly and gradually and deposit the foreignsubstances upon the bottom of the can; and to that end my inventionconsists in the several new and novel features of construction andoperation, which are hereinafter described, and specifically set forthin the claims hereunto annexed. It is constructed as follows, referencebeing had to the accompanying drawings, in which Figure 1 shows a sideview of the cooler complete, a portion of the shell of the can and theshells of the cooling device being broken away. Fig. 2 shows a verticalsection. Fig. 3 is a cross-section on line w x in Fig. 2.

Similar numerals of reference indicate corresponding parts.

l is a milk-can constructed substantially as shown and having a concavedbottom 2, said bottom being provided with a narrow channel 3, extendingfrom the center of the can radially and terminating in an outlet-pipe 4,which pipe is provided with a faucet operated in any ordinary well knownmanner.

The object in providing the radial channel 8 is for the purpose ofallowing the milk to be drawn off gradually and obviate its forming apool in the center, and thereby draw down the dust and dirt and otherforeign substances which congregate upon the top of the milk.

5 is a cover comprising an outer rim 6, a concaved bottom .7, extendingto the upright cylinder 8 and forminga trough into which the milk ispoured, and 9 represents perforations in the cylinder8 just above thepoint where it is secured to the bottom 7, and through whichperforations the milk in the trough l0 shoots inwardly and strikes theouter face of the cooling-chamber 11.

The cooling device comprises the cylinder or outer case 11, enlarged atits upper end, as shown at 12, and provided upon one side with an outlet13, all constructed substan-- tially as shown, and provided with legs14,

which'rest upon the top of the cylinder 8 in the cover. The body 11 hasa closed bottom, as shown.

15 is the inner cylinder or member of the cooling device, open at itsbottom and terminating in an enlarged top 16, and 17 represents feet orbrackets, secured as shown, and adapted to rest upon the'upper portionof the outer member or body 11, so as to support the inner body withinthe outer body, and 18 rep= resents lugs or arms to hold it in positionsubstantially in the center of the body, as shown. 19 is an opening inthe inner body, the operation of which is hereinafter described.

To operate my device in cases where I desire to use it for cooling milkby running water, I set the cooling device in the can, as abovedescribed, and allow the running water to pass down through the body 15and up through the outer can or body 11 and then out through the outlet13, thereby cooling the walls of the outer body 11 and keeping themcool. I then pour the milk into the trough 10, and as it spurts outthrough the openings 9 it strikes the outer wall of the body 11, causingit to be cooled almost immediately.

In the eventI desire to use the cooling device where running water isnot at hand, I

place cold water in a receptacle, and as the water becomes warm adjacentto the walls it is allowed to circulate in the cylinder or body 15through the opening 19.

Having described my invention, what'I claim, and desire to secure byLettersPatent, a cooling device suspended in said can, and isagainstwhich the milk is adapted to come in 1. A milk-cooler com prising a bodyhaving contact, asitpasscs through said perforations. an outlet, and acylinder open at both ends In witness whereof I have hereunto set my 5suspended therein, said cylinder being prohand this 30th day of August,1899.

vided with an opening for the purposes set i forth a L DAVID BOTHWELL.
